AMPLIFIER DESIGNAmplifier topology is the arrangement of parts in an amplifier design. Our car amplifier designs are broken out into 'classes' to help you choose the best amplifier to match your car stereo system . Each class has tradeoffs, making the various classes suited for different applications…like Class D or BD delivers higher RMS power, but undesirable noise in the higher frequencies making it better suited to power subwoofers.

CLASS D - High efficiency amplifier design that reduces current consumption from the charging system in your car or truck

FULL RANGE CLASS D -High efficiency amplifier design that reduces current consumption from the charging system

CLASS TA - The trans•ana topology operates the output stage with its full voltage gain, which allows the input stage to operate from a low voltage regulated supply. The signal is then shifted up in level to the high voltage section by the driver stage which forms an active node at ultrasonic frequencies. This results in a very stable, highly linear operation.

Not sure which is the best subwoofer for your car or truck? Below we have put each of our subwoofers to the test on a variety of performance metrics, so you can match the right bass to your mobile speakers and amps.

XMAX - The measured excursion of the subwoofer in one direction, with Peak-to-Peak covering its entiretravel. The more air a woofer moves the higher the SPL.

PEAK POWER - The maximum amount of amplifier power that can be applied to a subwoofer prior to entering into an unsafe operating scenario.

ANATOMY OF A SUBWOOFERVariations in the anatomy of a subwoofer dramatically changes their performance characteristics. An increase in voicecoil size coupled with a stronger cone material yields a higher power handling and increased output from your car speaker system . By combining quality materials with Rockford’s proprietary acoustic technologies, we have created some of the best car subwoofer lineups available that are sure to meet your system’s demands.

Basket - Also referred to as the subwoofer box, frame or chassis, this is the skeletal system of your car's subwoofer. Here to keep everything in its place.

Spider - Second part of the car's subwoofer suspension, connects the cone and voice coil to the basket and controls the travel of the cone assembly.

Voice Coil - The brains of the operation, directing the force from the magnet to push or pull based on the applied electrical signal from your car or truck.

Surround - First part in the car sub's suspension, attached to the cone to maintain the centering of the voice coil in the magnetic gap.

Cone - A.K.A the diaphragm, this is the voice of the speaker. Shape and material dramatically change tonality.

Magnet - The heart of the subwoofer, creating the force to push and pull cone assembly. Size, material, and design may differ, depending on performance goals.

We have designed a variety of our best car speakers to fit any audio system. Below we have highlighted the performance of each of our stereo speakers based on metrics like accuracy, frequency, and peak power so you know exactly what's going to blast out of your speakers and give you the most pristine for your car or truck.

Accuracy Score - Is derived from calculating the magnitude deviations from the speaker’s frequency response against a reference flat magnitude. response.

Frequency Response Range - The frequency response range or width tells you how high or low the speaker plays.

Peak Power - The maximum amount of amplifier power that can be applied to a speaker prior to entering into an unsafe operating scenario.

ANATOMY OF A SPEAKERModifications to the framework a car's stereo speaker significantly impact their sonic signature. Combining various materials will strengthen, add volume and resonate the music to a desired sound. By intertwining superior audio speaker designs with Rockford’s proprietary acoustic technologies in our speaker lineup we are sure to bring your music to life.

Tweeter - Composed of the same parts as our standard car audio speaker, surround, cone, voice coil, basket and magnet. Just on a smaller scale.

Crossover - Car audio crossover works like a switchboard, directing the audio signal through caps, filters and switches to the appropriate speaker in your car or truck.

Surround - First part in the speakers suspension, attached to the cone to maintain the centering of the voice coil in the magnetic gap.

Cone - A.K.A the diaphragm, this is the voice of the car's speaker. Shape and material dramatically change tonality.

Basket - Also referred to as the speaker box, frame or chassis, this is the skeletal system of your car's stereo speaker. Here to keep everything in its place.

Magnet - The heart of the car speaker, creating the force to push and pull cone assembly. Size, material, and design may differ, depending on performance goals.
